TREX search from specific folder + Abstract text

Hi all,

I am a SAP developper working with NetWeaver 04 SP11.

In fact I post 2 questions in this thread.

1) I would like to perform a search using TREX but giving a specific folder within the folder used by my index.

example: MyIndex is pointed to /documents

but I would like to search from /documents/MyStartFolder

---> How to do that ?

2)Second question is:

I need to get the abstract for each resource I found using my search.

---> Once again, how to do that ?

And I didn't find it reading some documentation about TREX in KM.

Thanks a lot for your help.

Best regards,

Emmanuel.
